Suzuki DF350A New 2024 Features vs Yamaha Mercury

What’s New in the 2024 Suzuki DF350A Outboard Motor?

The Suzuki DF350A outboard motor has received several key updates in its 2024 model compared to the 2023 version. These changes enhance performance, durability, and user-friendliness, making it a significant upgrade for boating enthusiasts. Here’s a comprehensive look at all the changes:

Integrated Steering System

The 2024 DF350A features a new integrated steering system, replacing the traditional setup that used an external steering cylinder. This system now incorporates the steering control directly into the outboard motor. This means fewer parts sticking out and potentially getting damaged. It makes the motor easier to install on various boats and reduces the chance of something going wrong with the steering because everything is now neatly contained within the motor itself.

Advanced Gear Case

The gear case has been redesigned to improve performance and durability. This new design includes a more efficient oil circulation mechanism that lowers the oil temperature and reduces the required oil volume from 3.2 liters to 2.8 liters. This change helps the motor run more smoothly and last longer. Lower oil temperatures and better lubrication mean less wear and tear on the gears, which is crucial for keeping the motor in good working condition for a longer time. It also makes oil changes easier and less messy.

SDSM+ App Integration

The 2024 model introduces the Suzuki Diagnostic System Mobile Plus (SDSM+) app. This app allows users to plan boating trips, check weather forecasts, and monitor engine conditions via a smartphone. For beginners, this app is like having a smart assistant for your boat. It helps you keep track of the engine’s health, plan your trips according to the weather, and get reminders for maintenance. This makes boating more convenient and helps prevent problems before they happen.

Noise Reduction

Suzuki has added noise reduction features, including a silencer and resonator, to suppress intake noise. A quieter engine makes for a more enjoyable and relaxing boating experience. You can talk to your passengers without shouting and enjoy the sounds of nature instead of engine noise.

Keyless Start System

The new keyless start system allows the engine to start with a key fob nearby, eliminating the need for a traditional ignition key. This feature makes starting the boat as easy as starting a modern car. It adds convenience and security, as the waterproof key fob ensures you won’t lose your keys in the water, and the immobilizer adds an extra layer of security against theft.

Tilt Limit System

A tilt limit system has been added to prevent the outboard from tilting beyond a selected angle. This system protects both the boat and the motor from damage by ensuring the motor doesn’t tilt too far. It’s a simple feature that can save you from expensive repairs.

Oil Passage Improvement

The oil passage has been improved to facilitate easier gear oil changes, eliminating the need to lift the boat for maintenance. This makes it much easier to keep up with regular maintenance, which is essential for the longevity of the motor. Easier maintenance means you’re more likely to do it regularly, which keeps your motor running better for longer.

Enhanced Durability Features

Several durability improvements have been incorporated, such as better gear lubrication and maintaining lower gear oil temperatures. These enhancements mean the motor can handle tougher conditions and will last longer. For someone new to boating, this translates to fewer breakdowns and a more reliable experience on the water.

Comparison With Yamaha & Mercury

Yamaha F350

The Yamaha F350 is known for its larger displacement with a 4.3-liter V6 engine, compared to Suzuki’s 4.4-liter V6. This provides the Yamaha with more low-end torque but makes it heavier (629 pounds for the short shaft model compared to the DF350A’s 727 pounds for the XL model). The Yamaha also boasts a high power-to-weight ratio, making it a popular choice for boats in the 20-35 foot range. However, the Suzuki DF350A’s dual-louver air intake system keeps the intake air cool and prevents engine knock, which can be crucial for maintaining performance and reliability over time.

While the Yamaha F350 offers a slightly better power-to-weight ratio, the Suzuki DF350A provides better fuel efficiency and enhanced durability features, making it a more reliable choice for long-term use​.

Mercury Verado 350

The Mercury Verado 350 is another strong competitor with a 2.6-liter inline-six engine and a supercharger for enhanced power. It weighs around 668 pounds, making it lighter than the Suzuki DF350A. The Verado 350 is known for its impressive acceleration and smooth power delivery, thanks to its supercharged design. However, the Suzuki DF350A’s fuel efficiency and advanced durability features, such as the dual-louver air intake system and better gear lubrication, make it a strong contender for those looking for a balance of power and efficiency.

The Suzuki DF350A offers better fuel efficiency and smoother operation compared to the Mercury Verado 350. Additionally, Suzuki’s focus on lower maintenance requirements and durability ensures fewer breakdowns and lower lifetime maintenance costs, making it a more economical choice for long-term use​.
